there is currently no scientific evidence supporting the existence of faster-than-light travel within our universe. The theory of special relativity, proposed by Albert Einstein, suggests that the speed of light in a vacuum, denoted as "c," is the ultimate speed limit in the universe. According to this theory, an object with mass would require an infinite amount of energy to accelerate to or beyond the speed of light.
Over the years, scientists have conducted numerous experiments and observations to test the limits of our understanding of physics and the possibility of faster-than-light travel. However, thus far, all empirical evidence has confirmed the predictions of special relativity, indicating that the speed of light is indeed a fundamental speed limit.
It's important to note that there are speculative theories and ideas that propose concepts such as wormholes, warp drives, or other forms of exotic propulsion systems that might allow for faster-than-light travel. However, these ideas remain purely theoretical and have not been experimentally confirmed or observed in nature.
Scientific understanding is continuously evolving, and new discoveries could potentially challenge our current understanding of physics. However, as of now, faster-than-light travel remains purely speculative and is not supported by empirical evidence or widely accepted within the scientific community.
